Q6. Cupcakes for the fair

This is for the older sister, who also likes maths, but loves dancing and singing much more.

There's a cake fair in Sidebay School every year, around Valentine's Day. This year there's a competition for the class that bakes and sell the most cupcakes. Fourth class won this year.

Between all the classmates in 4th class they baked 96 cupcakes. Two thirds ( 2/3 ) were sold for €1 each. Of what was left, half was sold in the sale for €0.50 each. The rest, I am afraid, was eaten by the hungry children in 4th class!

Your task is to find out how much money they make, but I am going to break down in little questions.

(a) How many cupcakes were sold for €1?

(b) How much money did they get for the €1 cupcakes?

(c) How many cupcakes were sold for €0.50?

(d) How much money did they get for the €0.50 cupcakes?

(e) How much money did they get altogether?

And an extra question just because:
(f) Assuming that each each ate one cake, how many children were they in 4th class?

Plus, minus, multiplication and division

Sometimes when you are given a problem, the first thing you have to do is to work out if you need to add, divide, multiply or subtract. That's what we're going to practise today.

Here's the story:

There are two teachers in the Sidebay school. Ms Lane and Mr Mura.

Ms Lane's class has 30 students. Ms Lane was given 90 blank pages to give to her students. Answer the following questions:

(a) If she distributed all the pages equaly among her students, how many pages would each student get?

Work out first which operation you have to do (multiply, divide, add or subtract) then write down your answer.

(b) If instead she decided to give each student only two pages, how many pages would she have left?

This questions is a bit harder because there are two steps to get the final result. Try to work out on your own, if you get stuck, ready the tiny clues below.

First find out how many pages the students got altogether. Then find out how many pages were left.

(c) Suppose Ms Lane gave two pages to each student, and gave the remainder to Mr Mura to give to his class. Mr Mura has 15 students in his class. How many pages did Mr Mura's students get?
